  • the bottom surface of the lid plate 3 comes into surface contact with the top surface of the ladle body 20 by swinging in accordance with the ladle body 20. Therefore, also in this case, the inlet 26 on the upper surface of the ladle body 20 is completely blocked by the lid plate 3.
  • the inlet 26 on the upper surface of the ladle body 20 can be completely closed by the lid plate 3, and therefore, between the lid plate 3 and the ladle body 20. It is possible to seal the storage space 21 of the ladle body 20 satisfactorily without any gaps.
  • the air lead-out pipe 27 for connecting the vacuum device 5 for depressurizing the storage space 21 is provided in the ladle body 20 of the molten metal transport ladle 2, but it is not necessarily limited to this. Instead, a pipe that communicates with the storage space 21 may be provided in the lid 3, and the vacuum device 5 may be connected to the pipe.

Abstract

L'invention porte sur un dispositif pour la distribution sous vide de métal fondu, lequel dispositif est apte à distribuer efficacement un métal fondu à une poche de transport de métal fondu. Un dispositif pour la distribution sous vide de métal fondu à une poche de transport de métal fondu (2) est équipé d'un corps de poche (20) ayant une ouverture de versage (26) dans laquelle est versé un métal fondu, et ayant également un espace de contenant (21) qui contient le métal fondu. Le dispositif comporte : une plaque de couvercle (3) qui est supportée au-dessus du corps de poche (20) de façon à pouvoir se déplacer verticalement, et qui peut fermer l'ouverture de versage (26) du corps de poche (20) de façon à sceller hermétiquement l'espace de contenant (21) ; un mécanisme de levage (4) pour déplacer verticalement la plaque de couvercle (3) ; un tuyau d'alimentation en métal fondu (6) disposé sur la plaque de couvercle (3), le tuyau d'alimentation en métal fondu (6) reliant l'intérieur et l'extérieur de l'espace de contenant (21) et étant apte à distribuer un métal fondu à l'espace de contenant (21) ; un dispositif à vide (5) pour réduire la pression à l'intérieur de l'espace de contenant (21) et introduire un métal fondu dans l'espace de contenant (21) à partir de l'ouverture d'aspiration (60) à l'extrémité avant du tuyau d'alimentation en métal fondu (6) ; et un mécanisme de support (7) pour supporter de façon à ce qu'il puisse pivoter le corps de poche (20).
